Many young parents assume that if they’re U.S. citizens, their kids are automatically all set – until they want to travel and try to apply for a passport and find out they don’t have the right proof of their child’s status.
Whether you’re dealing with a misplaced passport that needs to be replaced, mismatched names across documents, or missing citizenship paperwork, it can be frustrating to get it all in order. And if you’re missing just one piece of information, you can expect delays. If you’re planning to travel with kids anytime soon, here’s what you need to do to get this right.
Start with the right citizenship and identity documents
Before you shop for new luggage and start packing, make sure your kids have the correct foundational documents that prove their identity. For U.S. citizens, these documents are usually a valid passport, birth certificate, or Certificate of Citizenship.
If your child automatically became a citizen through your marriage and you never received formal documentation, you’ll need to file an N-600 application for Certificate of Citizenship to prove their legal status. Shillig Law’s in-depth N-600 guide explains who may already be a citizen through a parent, how to apply for a Certificate of Citizenship, and what that proof can mean later on for school, work, benefits, and even certain financial opportunities.
The N-600 application is an official form provided by the United States Citizenship and Immigration Services that proves citizenship. This process requires proof of your citizenship and your child’s birth certificate, custody, or adoption papers.
Key documents to carry with you
In addition to your child’s passport or Certificate of Citizenship, always bring their original birth certificate and a certified copy. Depending on where you’re traveling, a certified copy might not be acceptable. If you’re just traveling domestically you probably don’t need the original.
However, make sure to carry proof of your parent-child relationship. This can be an adoption decree, court order, or copies of your identification and your child’s birth certificate. For example, if your child was born in California, a certified California birth certificate can help confirm both identity and the parent-child relationship when additional documentation is requested.
Understand entry and exit rules
Every country has a different set of rules that dictate what they’ll accept as proof of identity, so find out ahead of time exactly what you’ll need. For instance, in some countries, dual citizens are required to present both passports, and some visa-free destinations still have strict documentation requirements.
Some countries ask for a notarized parental consent letter when only one parent is traveling with a minor, while others require dual-citizen children to travel on a specific passport. For example, many countries – including Canada, Mexico, and the Philippines – require written consent from the non-traveling parent if only one adult is accompanying the child. Some people get through after being questioned by officials, but many are denied entry for not having this letter.
Apply for passports and visas early
Passports and visas can take a long time to process, and that can be even longer for minors since both parents usually need to either appear in person or provide notarized consent. The average wait time for a U.S. passport in 2024 was 6-8 weeks, but expedited service can still take up to three weeks.
You also need to account for the potential of rejected applications. Many rejections are caused by incorrect photo dimensions or shadows. Always use a professional service like a UPS store or the U.S. post office for passport photos.
Never assume your child doesn’t need a visa just because you aren’t required to obtain a visa. Some countries require minors to obtain a visa even when their parents are exempt.
Submitting all the proper applications early gives you more time to handle breakdowns – like rejected applications – if they occur.
Prepare for the unexpected
Sometimes even doing everything right can’t prevent mistakes and mishaps. Airline or immigration officials can ask for additional papers, like proof of relationship or custody, especially if your child’s last name differs from your own. Bring extra forms of identification like a school ID, medical records, or even your child’s report cards just in case. And keep contact information for your embassy and a local attorney in case there’s a dispute.
Carry extra documentation whenever possible, regardless of how many times you’ve been to your destination. Rules frequently change and you could end up in a layover in a country you never intended to visit that requires you to deboard the plane and be processed through customs.
Preparation is the best way to avoid hassles
When you travel with your kids, having the right documents is just as important as keeping track of your plane tickets. Taking the time to secure and organize your kids’ paperwork ahead of time means fewer surprises and smoother sailing, regardless of your destination.
